SPINNING MACHINE WHIRL Original Filed April 23, 1934 INVENTOR ATTORNEYPatented Apr. 16, 1935 SPINNING MACHINE WHIRL- Thomas A. Darr,Cumberland, Md.

Application April 23, 1934, Serial No. 722,023 Renewed March 7,1935

3 Claims.

The invention relates to a spinning machine whirl and more especially toa ball bearing mount for a spinning machine whirl.

The primary object of the invention is the provision of a whirl of thischaracter, wherein a ball bearing mount therefor is had at the locationof the traverse, so that free movement is assured to the whirl andlubricant will be prevented from being thrown out of the bearing whenthe Whirl is rotated at high speed, and increased life is assured. 1

Another object of the invention is the provision of a whirl of thischaracter, wherein a bushing is carried by the spindle of the spinningmachine, the bushing being supported about a sleeve or tube which fitsthe said spindle and this bushing couples the traverse with the whirl,and in the assembly of the bushing, bearing balls are fitted therewithfor easy travel of the whirl.

A further object of the invention is the provision of a whirl of thischaracter which is simple in construction, thoroughly reliable andeflicient in its purpose, affording increased wearing quality, novel inassembly and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described in detail, illustrated in theaccompanying drawing, which discloses the preferred embodiment of theinven tion, and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a fragmentary top plan view showing the assembly inaccordance with the invention.

Figure 2 is an elevation partly in vertical section.

Figure 3 is a fragmentary vertical transverse sectional view.

Similar reference characters indicate correspending parts throughout theseveral views in the drawing.

Referring to the drawing in detail, A designates generally a portion, ofthe spindlerail of a spinning machine and B a portion of the traverse ofsaid machine, respectively, the said traverse being also known as a.lifting rail and being arranged above the spindle rail A. Removablyfitted in the spindle rail A is the vertical spindle I6, and thetraverse or lifting rail, in its arrangement above the spindle rail,loosely receives theret-hrough the spindle l0.

Upon the spindle ID is fitted the sleeve or tube 1 I which, near thelower end portion thereof, has

formed therewith an external annular shoulder l2 against which restsupper and lower inside and outside ball cones I3 and [4, respectively,these being held within a cup-shaped bushing l5 and having arrangedtherewith bearing balls IS. The bushing is formed with an external keyI! received in a keyway IS in the traverse or lifter rail B, so that thesaid bushing will be held against turning movement when fitted withinthe opening or clearance therefor in the traverse or lifting rail.Threaded internally of the bushing is its cap l8, this fitting the upperend of said bushingwhile at the lower end of the bushing is a packingvgland 19. The bushing exteriorly thereof is formed with the annular restflange which is at one side of the traverse or lifting rail, whileexternally threaded upon the bushing at the other side of said traverseor rail is the lock nut 2|, so that in this manner the bushing is madefast to the traverse or lifting rail. Upon the sleeve or cones therein,the outer end of the duct being closed by a removable plug 28;

The spindle rail has formed therewith a guide 29 through which works thelift rod 30 for the traverse or lifting rail B, the rod 30 being engagedwith a slide or jib 3| working upon or traveling on a guide 32 whichfunctions to prevent the twisting or turning of the lifting rail ortraverse, the whirl or pulley 22 being driven by a belt (not shown) andhigh speed of such whirl tends to twist or turn the traverse or liftingrail.

What is claimed is:

1. The combination with a spinning machine spindle and a lifting rail,of a tube loosely fitted upon said spindle, outside and inside conesarranged about the tube, bearing balls interposed between the outsideand inside cones, a bushing keyed in the lifting rail and enclosing saidcones and bearing balls, a cap fitting the top of the bushing, a packinggland at the lower end of the bushing and about said tube, a whirl fixedto the tube above the bushing, a cover for the upper end of saidbushing, the said bushing having a lubricant duct leading to theinterior thereof, and a removable plug closing the outer end of theduct.

The combination with a spinning machine spindle and a lifting rail, of atube loosely fitted upon said spindle, outside and inside cones arrangedabout the tube, bearing balls interposed between the outside and insidecones, a bushing keyed in the lifting rail and enclosing said cones andbearing balls, a cap fitting the top of the bushing, a packing gland atthe lower end of the bushing and about said tube, a Whirl fixed to thetube above the bushing, a cover for the upper end of said bushing, thesaid bushing having a lubricant duct leading to the interior thereof, aremovable plug closing the outer end of the duct,

and means cooperating with the lifting rail to prevent tilting orturning thereof.

3 The combination with a spinning machine spindle and a lifting rail, ofa tube loosely fitted upon said spindle, outside and inside conesarranged about the tube, bearing balls interposed between the outsideand inside cones, a bushing keyed in the lifting rail and enclosing saidcones and bearing balls, a cap fitting the top of the bushing, a packinggland at the lower end of the bushing and about said tube, a whirl fixedto the tube above the bushing, a cover for the upper end of saidbushing, the said bushing having a lubricant duct leading to theinterior thereof, a removable plug closing the outer end of the duct,means cooperating with the lifting rail to prevent tilting or turningthereof, and means exteriorly engaged on the bushing for securing it inthe
